A practical assessment of the moisture content of the wood fuel used is as follows. Wood, which is
to have a moisture content of 18-20%, must be seasoned for a period of 18-24 months or undergo a
drying process in kilns. As the moisture content of the wood is reduced, its calorific value increases,
which means financial savings - up to 30% of the total weight of wood needed for one heating season.
If wood with too high a moisture content is used for combustion, there may be an excessive consump-
tion of energy required to evaporate the moisture and the formation of condensate in the chimney or
combustion chamber, which affects the heating of the room.
Another negative phenomenon observed in the use of wood with too high humidity
is the phenomenon of creosote, a deposit which destroys the flue pipe, and which, in limited cases, can
ignite and cause a chimney fire.
It is therefore advisable to use hardwoods such as oak, beech, hornbeam and birch. Coniferous trees
are characterised by lower energy values, and burning them causes intense burnt glass.
MAINTENANCE OF FREE-STANDING SPACE HEATERS
Maintenance of the cooker and smoke ducts consists of the following guidelines. The periodic or sche-
duled maintenance of the cooker includes: ash removal, cleaning of the windscreen, cleaning of the
combustion chamber, cleaning of the flue pipe.
FLUE MAINTENANCE
The basis for the correct and safe operation of the cooker is a properly cleaned and maintained chim-
ney. The user is obliged to clean the chimney in accordance with current regulations. The frequency
of cleaning and maintenance depends on its insulation and on the type of wood used. The use of
unseasoned wood with a moisture content of more than 20% or coniferous wood will result in the risk
of a soot fire in the chimney due to the deposition of a thick layer of flammable creosote, which must
be removed regularly. An unremoved layer of creosote inside the chimney liner destroys the seal and
also contributes to corrosion.
There is therefore a need for periodic inspection and maintenance of the cooker and associated com-
ponents.
CLEANING THE FURNACE
Clean the steel parts of the cooker dry only. The cooker must not be exposed to moisture.
The firebox must be thoroughly cleaned and inspected before and after each heating season - leaving
ash in the ash drawer for a long period will cause chemical corrosion of the ash pan.
During use, periodically clean the firebox of the fireplace stove (the frequency of this activity depends
on the type and moisture content of the wood used). Use a poker, scraper, brush, fireplace hoover, or
ash separator to clean the combustion components.
CLEANING THE GLASS
The glass gets hot and should therefore be cleaned when the firebox has cooled down. Use only ap-
proved cleaning products for this purpose.
Use only approved cleaning products for this purpose (do not use them on the fireplace stove). Do not
use abrasive cleaners; these may scratch the glass.
Do not apply glass cleaning liquid directly to the glass, only to paper or a cloth. Dripping liquid may
cause corrosion of the cooker's steel components and loss of the cushioning properties of the gaskets.
DOORS/SEALS
The friction surfaces of the door hinges and locking mechanism should be lubricated occasionally
with graphite grease. Inspect and clean the entire cooker before each heating season. Pay particular
